Parameter
value: Specify the preference, ranging from1 to 255. By default, the value is 15.
Description
■ Use the preference command to configure the preference of IS-IS protocol.
■ Use the undo preference command to restore the default value.
Several dynamic routing protocols could run simultaneously on a router. In this
case, there is an issue of sharing and selecting the routing information among all
the routing protocols. The system sets a preference for each routing protocol.
When various routing protocols find the route to the same destination, the
protocol with the higher preference will take effect.
Example
Configure the preference of IS-IS as 25.
[SW7700-isis]preference 25
reset isis all Syntax
reset isis all
View

Parameter
None
Description
Use the reset isis all command to reset all the IS-IS data structures.
This command is used when LSPs need refreshing immediately. For example, after
area-authentication-mode and domain-authentication-mode commands are
executed, the old LSP still remain on the router. This command can be used to
clear them.
Related commands: area-authentication-mode,
domain-authentication-mode.
Example
Reset all the IS-IS data structures.
